STREET-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 409,492, dated August20, 1889.

Application filed December 3, 1888. Serial No. 292,489. (No model.)

To all whom it may concern..-

Be it known that I, SILAs R. OWEN, a citizen of the United States, and aresident of St. Joseph, in the county of Buchanan and State of Missouri,have invented certain new and useful Improvements in Street-Car Doors;and l do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the sam e, reference beinghad to the accompanying drawings, and to letters or gures of referencemarked thereon, which form a part of this specification.

Figure l is a vertical section across the end ot a car embodying myinvention. Fig. 2 is a sectional view taken on the line w w of Fig. l.Fig. 3 is a section taken on t-he lineof Fig. l. Fig. 4. is a section onthe line y fy of Fig. l. Fig. 5 is a section on the line z 2' of Fig. 1;and Fig. 6 is a detailed sectional view taken through one of the rollersof the doorcarrying bar.

This invention has relation to improvements in street-car doors; and itconsists in the construction and novel combination of parts, ashereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letterF. designates the door, and Athe metallic carrying-bar, the middle portion of which is secured to thetop of said door by means of bracketdiangers D D', and is provided withthe downwardly-inclined ends V V, projecting beyond each side of thedoor and carrying the grooved rollers B B.

C C represent the tracks, which are arranged one on each side of thedoor, and the rollers B B respectively, engage the trackways C C. Thedoor-carrying bar A is provided with downwardly-inclined ends V V inorder to reach the tracks C C', the latter being arranged as shown, orlow down when the tops of the windows upon the opposite sides of t-hedoor are below the top of the doorway.

K and K represent door-posts, and L and L posts of the car-body.

To the post L is secured the butter F, which is annular in form, and Gis a buffer-bracket secured to the edge of the car-door. Thisbutter-bracket is made in open form, proj ecting from the edge of thecar-door, so that it will reach the buer when the door is open.

At the end of the car, M represents the inside wall, and N the endpanels.

P designates a transverse bar forming lthe head of a window-frame, and Ris a sash in said frame.

S indicates the track-supporting bar, the lower portion of the front ofwhich is rabbeted to receive the bar P, so that the bar S is supportedby the bar P. The panel N is at its lower edge secured to the bar S. Theinner or rear portion of the track-supporting bar is also rabbeted toreceive and scat the metal track C or C.

Suitable fasteningscrews secure the parts together and in position asshown.

lhis method of construction is indicated for cars now built; but for newwork the bars S and P may be made in one piece. The grooved rollers B Bare provided with j ournal-screws Z, which are shouldered and secured inthreaded perforations in the ends of the bar A. After the journal-screwhas been turned into its seat in the bar A its endis slightlyheaded upagainst the bar to prevent it from beco1ning loosened. Thebrackethangers D D are channeled in their upper ends, forming squaredseats to receive the bar A, which is secured thereto by means of rivets.The shanks of the brackets are secured to t-he upper edges of the door,as shown. The upper portion of the bar A is clear above thebracket-seatsin order to allow it to move freely along the guide c, which is securedto a strip d on the framing-bar H of the car. In this manner it isdesigned to prevent lateral play of the door, the strip d also servingas a stop to prevent the carrying-pulleys from leaving their tracks. Thebuffer F is a ring of rubber, which is fastened in a concave recess in ablock f, which is secured to the corner-post of the carin properposition to receive the stroke of the door when open.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1sA

3. The combination, with the door-carrying bar A, havingdownwardly-inclined ends, its rollers, and the tracks arranged below thetop and on each side ofthe doorway, of the door, and the hanger-bracketsD D', connectedv to said bar and door and channeled to receive the barA, substantially as specified.

4. 'The combination, with the framing-bar II and posts L L', of therabbcted bars S, panels N, secured to posts L L and to the rabbetedbarsS, the bars P, letinto the bars S, and the tracks C C, secured inrabbets of said bars S, substantially as specilied.
